How to disable field overlays of particles in Blender 2.8?
If you go to the properties bar, under data, there is a display option which gives you the option of changing the size of the field outline.  You can set it down as far as .01, which is almost invisible.  It will at least make it far less annoying.



I found this using version 2.79, but hopefully that option is still available in 2.8
